avoiding tendonitus

I think I posted this in the wrong place, so I have now posted this here

Apologies

It has been a really long time since I have been here

Last time I had a really bad problem with my achilles tendon, it was pure agony walking

I went to a physio when I got back and had lots of massage and was dosed up with pain killers

(which dont really cure the problem, just covers the pain)

I was on a trip in africa, and yup we are going again

The last thing I want is a repition of it, so I have been doing a fair (okay, lots) of leg exercises

Squats 100k+, heel raises with weights, leg press with heavy weights, leg extentions with weights

Lots of stretching

Can anyone add anthing to any of the exercises I am doing ?

There will be lots of walking on this trip with an estimated of 40 miles a day over varied terrain and definately up a few hills

The whole will is estimated to last 8-9 months

Thanks for any replies
